Abstract

Four new species of Xiphocentron (Antillotrichia) Brauer, 1870 from the Atlantic forest are diagnosed, described and illustrated. All of them have a small mesal sclerite and a set of spines, differing in size, density and position, on the inner face of the inferior appendage. Moreover, tergum IX varies mostly in the shape of the posterior margin. Four species are described as new for science. Xiphocentron (Antillotrichia) copacabana sp. nov. is distinguished mainly by the projected basoventral margin of the inferior appendage, the spines are clustered in two regions and the quadrate posterior region of tergum IX. Xiphocentron (Antillotrichia) maracanan sp. nov is differentiated by the inferior appendage, with a strongly angled apical region of 90º. Xiphocentron (Antillotrichia) redentor sp. nov. differs by the inferior appendage, with a linear row of thick spines, and the tergum IX, with a posterior margin forming smoothly rounded lobes. Xiphocentron (Antillotrichia) tijuca sp. nov. is diagnosed by the subbasal region of the preanal appendage, which is markedly projected medially, and by the inferior appendage, which is thin subapically, enlarged apically and strongly bent dorsad.
